A test of an optimal stomatal conductance scheme within the CABLE land surface model
stomatal conductance scheme surface model
2015/3/5
Stomatal conductance (gs) affects the fluxes of carbon, energy and water between the vegetated land surface
and the atmosphere. We test an implementation of an optimal stomatal conductance mode...
Modeling stomatal conductance in the earth system: linking leaf water-use efficiency and water transport along the soil–plant–atmosphere continuum

The Ball–Berry stomatal conductance model is
commonly used in earth system models to simulate biotic
regulation of evapotranspiration. However, the dependence
of stomatal conductance (gs) on vapor ...

When coupling a superconductor to a normal conducting region the physical properties of the
system are highly affected by the superconductor. We will investigate the effect of one or two
superconduc...
